Abstract
Safeguards Assurance Analysis is a method to assist in the design and evaluation of safeguards systems. It can be applied to a facility before, during, or after construction. Before construction, it provides continuity throughout the design and evolution of the facility. It also provides a systematic means of selecting and evaluating the safeguard components for the system when the design and layout are complete. Generic models for the design and evaluation of safeguards systems to meet ERDA/NRC requirements for the protection of Special Nuclear Material have been developed, utilizing the Fault (Event) Tree technique. The technique allows the analysis of a conceptual or existing safeguards system in the context of conceivable threats to assure that the capability of the system meets design and regulatory requirements. The Fault Tree methodology also provides a structure for trade-off analyses to give a maximum cost effectiveness of the safeguards system within the design constraints.
